Make sure Roboto is not loaded

[rediche]

Some of the polymer paper components load Roboto. This should not happen since the page don't use the roboto font. There is some issues around on github that shows hackier ways to solve this, until those dependencies have roboto made into an opt-in for them.

Find out if the hackier ways are worth it, if so, remove roboto as a dependency and save some bandwidth and pageload time.
